Desktop CYBER (DtCYBER) emulates a range of Control Data Corporation CYBER mainframes
and peripherals in software.

DtCYBER is a high-performance
software emulation running on a modern Windows or Linux host. The emulator provides past
users of CYBER mainframes with an accurate emulation of all aspects of the legacy hardware. All
CDC operating systems and application software run unmodified on modern hardware. Performance of the
emulation on an average desktop PC is better than on legacy hardware.

DtCYBER emulates the following peripherals and associated controllers:

CC545 console

669 tape drives

679 tape drives

844 disk drives

885 disk drives

405 card reader

415 card punch

501 printer

512 printer

6676 terminal multiplexer

2550 NPU running CCP with ASYNC TIP

Two-port multiplexer (CYBER 170 model 865)

The emulation has been verified on the following CDC operating systems or maintenance/diagnostic systems:

SMM 4.0

CMM 1.2A

KRONOS 2.1

NOS 1.2

NOS 1.3

NOS 1.4

NOS 2.1

NOS 2.3

NOS 2.4.2

NOS 2.5.3

NOS 2.8.1

NOS 2.8.2

NOS 2.8.7

NOS/BE 1.5

SCOPE/Hustler

DtCYBER does not run NOS/VE which requires virtual mode available only on CYBER 180s.

Note: No CDC operating system is included with DtCYBER. Users must supply
their own OS installation tapes to make use of the emulator. Please contact
Tom Hunter
for help with conversion of existing 9-track tapes to TAP disk images used by the emulator.
